Los Angeles: Protests against seed giant Monsanto are getting under way across the US and in dozens of other countries. "March Against Monsanto" organizers say they're calling attention to the dangers posed by genetically modified food and the companies that produce it. Protests are planned in more than 250 cities on Saturday.

Some believe they can lead to health problems and harm the environment. Opponents have pushed for mandatory labeling, though the federal government and many scientists say the technology is safe.

Monsanto Co., based in St. Louis, said on Saturday that it respects people's rights to express their opinion, but believes its seeds help farmers produce more food, while conserving water and energy.(Agencies)
